多元分离体系在膜内传递过程中 ,其分离特性不仅受渗透组分与膜材料之间的相互作用的影响 ,同时也受控于膜内组分间的耦合效应的影响 .研究了渗透组分在膜界面上的溶胀分配关系 ,从理论上描述了溶胀过程中的耦合效应 .讨论了渗透组分在扩散传递过程中膜内各组分所形成的浓度场分布 ,以此研究了强相互作用下膜过程中的传递行为 .对乙醇 水体系在壳聚糖膜和硫酸交联壳聚糖膜的渗透汽化实验结果表明了耦合效应的存在以及对分离性能的影响
In the process of membrane transfer, the separation characteristics of the multivariate separation system are not only affected by the interaction between the permeation component and the membrane material, but also controlled by the coupling effect between the components in the membrane. And the coupling effect in the swelling process is theoretically described.The distribution of the concentration field of each component in the membrane during the diffusion process of the permeation component is discussed, The results show that the coupling effect and the effect on the separation performance of ethanol-water system in chitosan film and sulfuric acid crosslinked chitosan film
